BISSELL® Little Green® Max Pet Portable Carpet and Upholstery Deep Cleaner, Car/Auto Detailer, with Self-Cleaning Tough Stain Tool and Pet Hair Removal Tool (3860)
BISSELL Little Green® Max Pet Review — The Ultimate Portable Deep Cleaner for Pet Messes
Pet messes happen—muddy paw prints, accidents on carpets, embedded dirt in car seats, and stubborn stains that refuse to go away.
The BISSELL® Little Green® Max Pet Portable Carpet and Upholstery Cleaner is designed specifically for pet owners who need fast, powerful, and convenient cleaning.
With superior suction, self-cleaning tools, and dedicated pet stain technology, this compact machine offers deep-clean performance that rivals full-size extractors.
Superior Suction & Deep Cleaning for Real Pet Households
The BISSELL Little Green Max Pet is engineered to deliver 30% more powerful suction than competing portable cleaners.
This extra power ensures faster extraction of liquids, odors, and dirt trapped deep in carpet fibers, upholstery, stairs, and car interiors.
When paired with BISSELL’s PET PRO OXY Spot & Stain formula (included in the box), the machine removes tough pet stains instantly and permanently—especially urine, vomit, mud, and set-in organic messes.
Self-Cleaning Tools for a Better Experience
One of the standout features of this model is the self-cleaning Tough Stain Tool.
With a single press, the hose and tool flush out leftover dirt, pet hair, and residue—keeping the cleaner hygienic and odor-free.
You also get a dedicated Pet Hair Removal Tool designed to pull up stubborn fur embedded in fabric.
Engineered for Convenience, Speed & Simplicity
Despite its compact size, the Little Green Max Pet is incredibly user-friendly.
The lightweight body, extended cord, and long hose make it easy to reach stairs, corners, car seats, and under furniture.
BISSELL’s two-tank technology keeps clean and dirty water completely separate, ensuring you always clean with fresh solution.
Filling and emptying the tanks is straightforward, and both tanks are designed to resist odor buildup.
- Spray cleaning solution onto stains
- Scrub using the built-in brush tools
- Suction lifts dirt, liquids, and odors instantly
Perfect for Homes, Cars & Pet Owners
